安装python环境python = 3.5.2

Question

I tried to create a conda python environment with python=3.5.2 and get bellows errors.

1. How can i add a custom link for installation ? eg https://anaconda.org/anaconda/python/3.5.2/download/win-64/python-3.5.2-0.tar.bz2

conda create -n eapp_env python=3.5.2

Answer 1

It looks like only 3.5.4, 3.5.5, and 3.5.6 are available on the main/win-64 index of the anaconda channel. I am not sure why they removed previous versions of 3.5.

You can switch channels to conda-forge, which still has all of the versions available.

conda create -n eapp_env python=3.5.2 --channel conda-forge

Just as an FYI typically the sub-sub-version of a package only has minor updates and will not affect anything else in your environment.
